Lucifer (Does that count as a warning?), so language, probable violence, Hell-shenanigans, mentions of torture if not actual torture
Notes:
Sorry this is so late. I am the worst. No rush on this!
Lucifer wasn't a parent. He looked after Joshua, only because the being had a part to play in the end. But when it came to actual fathering he usually ignored him. Why Satan had suddenly decided that it was super important to find their child was beyond him. As far as he knew, Joshua wasn't able to die until the Apocalypse came.
But because he liked the thought of being owed a favor from Satan he'd set out. The city was vast though and one immortal amongst many was annoying to find. In the end he set Legion out, but they'd come back with nothing. He couldn't get at the Saints, not eager to find out how much Michael wanted vengeance, but he could get at Wrath.
He'd noticed she'd become less vigilant and wary, which he felt like the perfect opportunity to strike. He figured since she was fucking a Saint, she could at least give them the courtesy of letting them know if they knew anything. If not, he was sure he could persuade her.
Legion had been good enough in their hunt and found out where Wrath worked. He could feel his brother's wards miles off and he sneered at the building before leaning in an alleyway and waiting. Eventually he waved Legion off, not wanting their particular distraction, and watched.
It didn't take too much longer before he spotted Wrath. He waited until she was before the alley before stepping in front of her. "Hello Wrath. If you run, I'll find your little Saint boyfriend and see how many times I can kill him. Be a good girl and stay."
